Anyone else been having disrupted sleep patterns lately?

Been having them for a month or so. At first I thought it might be releated to the fact that I was a bit ill, but maybe there are some other explanations as well. Lately I fall asleep around 5-6 AM, but that leaves me 1-2 hours sleep before I have to wake up for work. Usually, on work days, I go to bed around 11-12 PM. It has happened to me twice during the last month and never before. It usually happens for 3-4 days in a row and then, probably because I was already very sleepy not having slept for several days, I finally get back on track.

I just started thinking about it and it being releated to the bird/fish deaths and the polarshift?

...but it could also be rleated to a million other things, so I am just curious. The weird thing is that I know my brother also has had sleeping trouble lately during the last month.

Just to be clear I am from north-eastern Europe.
